请各位帮我把两个 vb6.0写的两个函数转换成C#该怎么写？我找不到相应的函数？多谢！

如题，请大家帮帮我把如下的两个函数用C#怎么写！！？？

'将UNICODE转换中文
Public Function Unicode2AscII(ByVal s As String)
On Error Resume Next
Dim i As Integer
Dim r As String
For i = 1 To Len(s) Step 4
r = r + ChrB("&H" & Mid(s, i + 2, 2)) & ChrB("&H" & Mid(s, i, 2))
Next
Unicode2AscII = r
End Function

'将 ASCII 码（中文）转 换成 Unicode码
Public Function AsciiToUnicode(smsg As String) As String
Dim si, sb As Integer
Dim stmp As Integer
Dim stemp As String
sb = Len(smsg)
AsciiToUnicode = ""
For si = 1 To sb
stmp = AscW(Mid(smsg, si, 1))
If Abs(stmp) < 127 Then
stemp = "00" & Hex(stmp)
Else
stemp = Hex(stmp)
End If
AsciiToUnicode = AsciiToUnicode & stemp
Next si
AsciiToUnicode = Trim(AsciiToUnicode)
End Function

好象你自己要添加参照MIRCSOFT VB的呀

Microsoft.VisualBasic.Strings.AscW()

在 C# 论坛解决了这个问题！多谢各位！马上结帖！

编码转换都在
System.Text.Encoder命名空间。
转换很容易的。

public object Unicode2AscII(string s)
{
// TODO: NotImplemented statement: ICSharpCode.SharpRefactory.Parser.VB.AST.OnErrorStatement
int i;
string r;
for (int i = 1; i <= Len(s); i += 4) {
r = r + ChrB("&H" + Mid(s, i + 2, 2)) + ChrB("&H" + Mid(s, i, 2));
}
Unicode2AscII = r;
}



public string AsciiToUnicode(string smsg)
{
int si;
int sb;
int stmp;
string stemp;
sb = Len(smsg);
AsciiToUnicode = "";
for (int si = 1; si <= sb; si++) {
stmp = AscW(Mid(smsg, si, 1));
if (Abs(stmp) < 127) {
stemp = "00" + Hex(stmp);
} else {
stemp = Hex(stmp);
}
AsciiToUnicode = AsciiToUnicode + stemp;
}
AsciiToUnicode = Trim(AsciiToUnicode);
}

楼上，在C#里面好像没有AscW这样的函数啊！
